[sldev] A couple of inventory UI fixes for Snowglobe

[Thickbrick Sleaford]

Now that Snowglobe has a Worn Items inventory tab, I have two small patches 
that seem like a natural follow-up.


SNOW-232:
The check-marks in the Sort menu aren't being updated when switching between 
tabs. This bug becomes more confusing to users the more tabs there are.

The fix for this is simple (update the controls when switching between tabs), 
and was reviewed by Techwolf. So if there are no objections, I will commit it 
in a few days.


SNOW-251:
This is a patch to make the sort order of the Worn Items and Recent Items tabs 
persist between sessions.
It adds a new persistent setting "WornItemsSortOrder", and uses a pre-existing 
(but unused, so far) setting "RecentItemsSortOrder".

To me, this is a natural follow-up to the Worn Items tab (but is pretty 
useless without the fix in SNOW-232)

My questions are:
* The RecentItemsSortOrder setting is already persisting, but it is being 
overridden to "sort by date" on every login. Is there some usability reason 
that might have been done?
* Any objections?
* Please review the patch.

NB: "sort order" here means a bitfield of all the options in the Sort menu.
